What will you be doing?

We are looking for you, a senior modeller, who translates concepts into mathematical models to make judgements on the circularity of ecosystems and as such will make a crucial contribution to the transition towards a circular economy. Socially relevant issues that TNO investigates in projects and consortia. And for which you, as a senior modeller, can act as the right catalyst. Can you picture it?

Your primary focus is on developing new methods and tools that will lead to knowledge, information and insights that take companies, governments and communities forward to a more sustainable circular economy. Or even help them accelerate this transition. Together with internal and external parties you know how to build and extend such a model suite. This also means that you work with others to write high-quality and impactful project proposals. You do this together with the PMC Cluster/Roadmap driver of Impact Assessment.

What do we require of you?

Communicating internally and externally. With members of the project team, business consultants and standard bearers in the field at TNO. And with the public, with various media that might sometimes make matters difficult for you. This stimulates you, and you know exactly how to deal with such situations. Managing stakeholders’ expectations? You are good at that, also in face of resistance. Because you have your feet firmly on the ground. What else can you offer?
  • You have a background in econometrics, mathematics, chemistry or physics and you have a PhD in modelling impact assessment (social, economic, environmental), material flow, or other modelling methods relating to the transition to a more sustainable circular economy.
  • You have sufficient methodological knowledge (hybrid modelling, scenario construction, model dynamisation and/or the translation from national to regional model forms) to develop new methods and tools to monitor, evaluate or predict the transition to a more sustainable and circular economy.
  • Your extensive experience enables you to come up with relevant new questions to be answered in the transition to a sustainable, more circular economy and to translate that into a model.
  • You are part of and contribute to the formation of the knowledge team and the knowledge strategy.
  • You have an extensive network and you know how to use it in forming consortia for project proposals and you can expand your network to the parties that are relevant to our work.
  • Mentoring of mediors and juniors in projects comes naturally to you in your role. You actively contribute to their professional development, enabling them to grow to a higher level. 
  • You have an excellent command of Dutch and English, both written and spoken. 

What can you expect of your work situation?
